:1 Anrisxmnme Beit known that I, WILLIAL'I Ei Bnnn acitizen .ofhthe United States, residing at Elizabeth, in' the countyof Union and State of New Jersey, have invented certain new -and useful Improvements in'Antiskidding Attachments for Tires, of which the-follow ing a specification,"- reference being had to the accompanying drawings.

This irivention comprehendsice'r'tain new and useful improvements. in antiskidding attachments for th tires of automobile, motor truck, or other vehicle wheels, and the invention has for its; primary object a sim -pl'e, durable and efiicient construction of device of this. character, the parts of which are so arranged and'adapted to be attachedto the wheel that each part will be practically independenbof all of the others, whereby any desiredjnumber of chains, and their correlated parts maybe-used according tothe. 'particular-requirements of the case, and whereby when one chain-or its attached deyicesbecom'e broken, that will not afiect in any wisethe others.

The invention also-has-for its object-an.

attachment-of this character which maybe easily secured to the wheel, which will'be securely held in po'sititm .as long as desired. without liability of accidental d splacement, and which may be easily j'remove'd or I stripped from the wheelwhen not required.

And the invention also aims to generallynnprove devices of-this class so as to renderthem more useful. and commercially. dearable. '7 I With these and other objects in view, as

v will more fully appear as the description inafter .8

. scription proceeds, the invention consistsin certain tions' of the parts tint '1 shall hereinafter fully describe and claim.

For a full understanding of the invent-ion, referenceis to behad to' the iollowing deand accompanying drawing, in which*.--v p Figure'l, is' a side elevat1on of a wheel showing my attachment applied thereto; Fig. 2, is a transversesectiona view throu h the tire, rim and .fell showin one of t e attachments; Fig. 3, ls'adetai perspective 'view of one ofthe studs or projections hereifically referred to; and Fig. 4,- is a detai view of one of the clamping bars.

Each of my improved anti-skidding" at tachlnents comprises a flexible tread memher 1 which is-preferably composed of any desired number of connected links, asshow'n,

the .end links being. preferably of"b1 'ass',

while. the intermediate or'ieniaining' are of steel. The end links, designatedfQ,

are engaged in apertures 3 thatare formed. 1n angular anchoring bars or fastenersj that.

are preferably iorined of S some other resilient metal or-material. Prefera'bly," these bars 'orfasteners 4 are identical in structure, whereby they drainage- -operation=-of a single die. 'The' a. urea-8 ehangeabl and can be cheaply ,mtLEby the are formed in the bars or 'fastene' one extremity thereof and eachbar4 is'also 4 near'f formed in its opposite end with a plurality of bpenings 5 arranged ina longitudinal'se i pyo just-ing the sme magY Ywe to tires of difierent sizea- 6 designates projections which, in the" .present'instance, are in the form oi studs' secured in anydesired way to the fel ly If!v a the wheel and projectin inward in a radial direction therefrom.

stance, these studs ar provided a one end, with screw threaded portions, whereby they Y n 'the present may be easily inserted into the felly, but it is to be understood that the invention is not limited in: this regard, 'but't-hat any manner of securing the studs in place maybe employed. Preferably, there is one of these studs 6 between. every, two s okes of the" wheehlalthough it is'to be an erstood that the invention is not limited-in that regard either.

The studs 6, as-will be clearly'seen from the drawing, have their inwardly projectin ends formed-gwith somewhatrounded an ornamental heads 8' althou h the heads may be omitted), and t se-he'a s,-as is manifest, produce annular shoulders 9, the-studs tapering toward the shoulders from the main. portion ofthe studs contiguous to-the inner edge-of the felly. Preferably, .the

studs are encircled by washers 10' of felt. leather orthe like. a

From the foreg'oing description in com nection with the accompanying drawing-it. will be understood that in thetlpractical up plication of my invention, i-gvwhe el nipped with aseries oi-the-studs .6, and

w euever it is-desired to guard'ageinat j the openings 5, according to the width or diameter of the tire and its felly and rim,

v adjustment of the parts being thereby taken care of. Owing to the spring characteristics 1 of the bars or fasteners 4, they will be securely held in place, while at the same time, the tread members 1 will-not necessarily be i stretched tautacross the tire, in which event-1,1

. 7 they mightinjure it, neither is the. paint or enamel of the felly injured or marred in any way by the use of my attachments, as the bars or fasteners 4 will not engage rub-:-

1 upon the side faces of the felly.

. It. will thus be seen that I have provided a very simple anti-skidding attachment for tires, one that can becheaply manufactured and one which possesses to a marked degree, the advantageous characteristic of capability of quick attachment and detachment. Furthermore, as each tread member 1 with its bars or-fasteners 4 is separate from and independent ofall of the other bars and their connected tread members, it is obvious that any desired number of the devices maybe 35. sed according to the condition of the ground over which the vehicle is passing, and that should one of the devices become broken, that will not affect any of the others andthe broken one can be repaired or replaced at asma-ll cost, whereas with the ordinary tire armor or anti-skidding chain in which the transversely extending tread v'members are all connected together by circumferentially extending chains, it is quite common to lose the entire device should any link become broken.

It is to be observed that the outer end portions 4 of the bars or fasteners 4'are fiexed upwardly normally at substantially" right angles and that the bend 4 'of such fiexure is positioned relatively to the post 6 a distance less than the distance from the plane occupied by the post 6 to the outer edge of the felly 7 with which the flexed portion 4 65 is adapted to contact, it being understood that in referring to the felly 7 the rim secured thereto is included. As the bar or fastener 4 is produced from spring metal it will be obvious that the flexed portion 4" .will be distended when the fastener is placed in operative position and thus creating a frictional means whereby the bar or fastener the overlapped the scope of the invention, appended claims,

' signature in the 4 'will be prevented from displacement as a resultant binding will be created betweenthe bar or fastener 4 and the post'6. If from any cause the bars or fasteners 4 may be caused'to move outwardly of the post 6, it will be under-stood'that the resiliency possessed by the same to spring in contact with the head 8 whereby the bars or fasteners are effectu ally held against displacement. By using washers 10- on the studs 6, it is obvious that or fasteners will not rest directly upon the felly and this. feature also tends to preclude any liability of marring the paint.

While the accompanying drawing illustrates what I believe to be the preferred embodiment of my invention, it is to be understood that the invention is not limited hereto, but that various changes may be made in -'--the construction, arrangement and propor' tions of .the parts without departing from as defined in the What I claim is 1 1. In combination with the felly of a wheel, a post inwardly directed from the felly, and a normally substantially rightangular chain fastener of spring metal provided with a perforation in one of its porthe bars or fasteners 4iwill cause ends of the 1 anchoring b'ars v tions to surround the post, the opposite portion of the fastener tionally engage the felly, the distance between the aperture ofthe fastener in engagement with the post and the bend thereof being less than the distance between the being adapted to fric-' post and the edgesurface of the felly with which the fastener contacts.

2. In combination with the felly of a wheel, a post inwardly directed from the felly, and a normally substantially right angular chain'- fastener of spring metal provided with a perforation in. one of its portions to surround the post, the opposite portion of the fastener being adapted to frictionally engage the felly, the distance between the aperture of the fastener in engagement with the post and the bend thereof being less than the distance between the post loo and the edge surface of the felly with which the fastener contacts, the freeen'd portion of the post being provided with a head insertible through the aperture of the fastener and serving as a positive means whereby the fastenermay be held against displacement from the post.

In testimony whereof ,I hereunto affix my presence of two witnesses. WILLIAM E. BU'D'D. Witnesses: e
